Operating Environment
1. Do not use in an atmosphere having corrosive gases,
chemicals, sea water, water, water steam, or where
there is direct contact with any of these.
2. Do not use in an environment where flammable gas
or explosive gas exists. Usage may cause a fire or
explosion. The products do not have an explosion
proof construction.
3. Do not use in a place subject to heavy vibration
and/or shock.
4. The valve should not be exposed to prolonged
sunlight. Use a protective cover. Note that the valve
is not for outdoor use.
5. Remove any sources of excessive heat.
6. If it is used in an environment where there is
possible contact with oil, weld spatter, etc., exercise
preventive measures.
7. When the solenoid valve is mounted in a control
panel or its energized for a long time, make sure
ambient temperature is within the specification of
the valve.
1. Temperature of ambient environment
Use the valve within the range of the ambient temperature
specification of each valve. In addition, pay attention when
using the valve in environments where the temperature
changes drastically.
2. Humidity of ambient environment
• When using the valve in environments with low humidity, take
measures to prevent static.
• If the humidity rises, take measures to prevent the adhesion of
water droplets on the valve.
Maintenance
1. Perform maintenance inspection according to the
procedures indicated in the operation manual.
If handled improperly, malfunction and damage of machinery or
equipment may occur.
2. Removal of equipment, and supply / exhaust of
compressed air
When components are removed, first confirm that measures are
in place to prevent workpieces from dropping, run-away
equipment, etc. Then, cut off the supply pressure and electric
power, and exhaust all compressed air from the system using
the residual pressure release function.
For 3-position closed center, exhaust the residual pressure
between the valve and the cylinder.
When the equipment is operated after remounting or
replacement, first confirm that measures are in place to prevent
lurching of actuators, etc. Then, confirm that the equipment is
operating normally.
3. Low frequency operation
Valves should be operated at least once every 30 days to
prevent malfunction. (Use caution regarding the air supply.)
4. Manual override
When the manual override is operated, connected equipment will
be actuated.
Operate after safety is confirmed.
5. If the volume of air leakage increases or the valve
does not operate normally, do not use the valve.
Perform periodic maintenance on the valve to
confirm the operating condition and check for any air
leakage.
1. Drain flushing
Remove drainage from the air filters regularly. (Refer to the
specifications.)
2. Lubrication
In the case of rubber seals, once lubrication has been started, it
must be continued. Use class 1 turbine oil (with no additives),
VG32. If other lubricant oil is used, it may cause a malfunction.
Please contact SMC for information on the suggested class 2
turbine oil (with additives), VG32.
3. Manual override operation
When switching a double solenoid valve via the manual override
operation, instantaneous operation may cause the
malfunction of the cylinder. It is recommended that the manual
override be held until the cylinder reaches the stroke end
position.
